Experimental Petrology

The UAF Experimental Petrology Lab provides a state of the art research facility for studying magmatic processes at high temperatures and pressures. The Lab houses the following equipment:

Rockland Research piston-cylinder apparatus capable of up to ~1 GPa pressure, and ~2000 C temperatures. It is typically used for phase equilibria experiments recreating magma crystallization and equilibriation processes in the deep crust to shallow upper mantle.

1 Atmosphere Gas Mixing furnace: This apparatus is used for crystallization and melting experiments under controlled oxygen fugacity conditions at atmospheric pressures. The apparatus is built using a DelTech vertical tube furnace and run using CO2-H2 gas mixtures to control fugacity.

4 rapid-quench capable cold-seal pressure vessel apparati: The cold-seal apparati are fitted with a special extension that allows rapid quenching against the water-cooled pressure seal, using a magnet controlled sample holder. These apparati allow for crystallization and vesiculation kinetics studies with rapid quenching.

2 TZM/MHC alloy cold-seal apparati: DelTech furnaces are paired with Titanium-Molybdenum-Zirconium or Molybdenum-Hafnium-Carbide pressure vessels for higher temperature phase equilibria and kinetics studies. The MHC vessels are capable of temperatures up to ~1200 C at pressures to 2 kbar.
